pigletmania - just wanted to say I think you've done well for keeping your cool in a bit of a 'heated' discussion...many lesser MNers have fallen here before
Also wanted to add my experience of 'extended' bf:
I BF my first child until she was 12/13 months. Mostly I stopped because I was tryinbg for another baby, but actually I had never even considered feeding beyond 12 months. Nobody I knew did...and I just didn't think about it at all. I'd heard people say "Once they can ask for it, they're too old" and I thought "hmmm, yes, maybe.."
With my second child, I struggled with feeding but managed to get past 6 months, and then planned to continue to 12 months or so...BUT, this time I knew people who were BFing their 15, 18 month olds, with no plans of stopping. I wasn't trying to conceive, and my son was a high need baby and very relient on BFing...and so I continued...and continued...and I finally stopped when he was almnost 2, bascily because I was getting fed up with it!
It did not 'feel' weird at all to be feeding him at almost 2. I guess because he had grown slowly over the years - it wasn't as though somebody had handed me a toddler and said "feed this!"
Looking back, I would never have imagined I feed so long. It was a combination of seeing other Mums feeding longer, hearing about extended feeding mums of MN, reading about all the very significant health benefits to baby and Mum, and a different baby, who showed me very clearly that he needed feeding for longer than 12 months!
For me, it was deifinately something I should not have knocked until I tried it!
I am 20 weeks with my third child now...who knows what I will do? TBH I do feel a bit 'funny' about the thought of feeding beyond 2.5 /3 years...BUT, I know now that I may feel very differentlyu about it in time to come, and any hangups I have are my problem, and a cultural problem, not a problem with breastfeeding.
I hope that story encourages others who are not sure about 'extended; BFing
